Thanks everyone for the help. So, as much as i get, the champion with free archetypes (which our DM is ok with) would be the best option.
Now the choice lies on what kind of champions should i use? What archetypes will fit the best for this situation?

Thanks for all the help, really appreciated.
So, as I can see, lot of you are suggesting to go for a Champion. Anything particular about how to build it to be usefull for this party? As i said i'm a novice and i never builded a Champion so if any skill/feat could help me make it more usefull for the party, let me know.
(We use the free archetype rule and, since some of you talked about that, no the other 2 party members are not planning to invest in healing stuffs :<)

Hi everyone. I do want to thanks in advance everyone who will spend some of his time reading my walltext and trying to help me.
I'm a novice with Pathfinder 2e, i only played DnD 3.5 and DnD 5e for a while, but then a friend of mine decided he wanted to be DM for a Pathfinder 2e preset adventure (he's a novice too and he loves to be a DM, so he's trying to learn). We were supposed to start as a 4 men party for a 4 members adventure from level 1 to 4 but we endend up being 3 because of work and RL problems.
Our DM said to go for classes we would like to play and not to worry about the campaign, he would have adjusted the difficulty based on our party, so my 2 friends decided to go for a ranged rogue and a sorcerer so we were missing a melee dps/tank/healer. Being our DM a novice too I thought he may have some problems adjusting the difficulty so i decided to go for a versatile class who would have helped the party and decided to go for a warpriest (kinda tanky, good healing options and some melee dps at low levels).
Turns out our DM is not good adjusting difficulty so we ended up having encouters for a 4 men party with us being only 3 and me being the only frontliner taking damage from all the enemies. Useless to say I end up being on the ground everytime (been lucky with my death rolls) and i can't do anything but heal sometimes and stay on the ground.
We think he noticed this because he said that with the new preset campaign we will start after this one (we are almost at the end luckly) we may keep the characters but change classes if we describe that with a background addition.
So my question for you all is: Considering my 2 party friends won't change their classes and that our DM wants to keep going from level 1 to 20 with preset adventures at the start and then maybe do something custom-made when he will be more confident with the system, what you veterans advice me to play with this party and how should i build it? Because i don't think warpriest was a good choice to make but it looked the more versatile option to me, being a novice. (We are planning to use all manuals to create characters).
Thanks again in advice for everyone who will try to help me.
